Teachers in Germany also have 19.5 (now 18.5) years of education. There are few jobs that require more (e.g. doctors).
So, how much percent in pension payments for teachers would the German taxpayer save if the state required, say, one year less teacher education?
The question does not make sense to me. It‘s a market. You require a masters degree and an additional tough 1.5 years of training? Better pay me well, through salary or benefits. Let‘s not kid ourselves: most of us (highly qualified) white collars in the private sector enjoy some additional retirement scheme and can reach much higher salaries.
Why shouldn't a teacher have a high pension? I can't think of a job that's more important to the long-term viability of a country than that of a teacher.
A high pension is one thing. A pension that's higher than the salary of most of the population is quite another.
I'm not arguing that teacher shouldn't be paid well, I'm saying that the state is paying it's officials very well. Not because of the jobs they do, but because of who employs them. Teachers in Germany that are not employed by the state get significantly less.
That's expected, the state pays it's employees very well for a multitude of reasons, but primarily: to buy their loyalty, to make them less susceptible to bribes, and to encourage stability. It also has no reason not to, there's no competition.
I don't know the Danish situation, but e.g. a teacher in Germany will have a pension that is higher than the salary of 70-80% of the population.
